概括
神经心理学通常需要两个性能有效性测试 (PVT) 失败才能认为答案无效. 然而,失败的Test of Memory Malingering (TOMM),特别是特定的分数,可能是足够的证据本身的无效.
科学领域:
- 神经心理学 神经心理学
- 法医心理学 法医心理学
- 心理评估 心理评估
背景情况:
- 神经心理学的标准指导方针表明,为了确定响应无效性,需要两个性能有效性测试 (PVT) 的失败.
- 本研究探讨了对这一规则的潜在例外,考虑到使用的特定PVT和性能缺陷的严重性.
研究的目的:
- 确定单个PVT上的故障是否可以作为响应无效的充分证据.
- 检查不同PVT上的故障之间的关系,特别是内存恶意测试 (TOMM) 和可靠数字间隔 (RDS) 的测试.
- 评估TOMM或RDS上的特定故障值是否预测了额外的PVT故障.
主要方法:
- 261名成年参与者完成了包括4-12个PVT在内的神经心理测试电池,其中始终包括TOMM和RDS.
- 进行了统计分析,以评估单个PVT的故障之间的关联.
- 分析了TOMM,RDS和其他PVT之间的故障率和故障一致性.
主要成果:
- 16.5%的人没有通过TOMM,其中97.7%的人也没有通过另一项PVT.
- 14.2%的人没有通过RDS,其中75.7%的人也没有通过另一项PVT.
- 试验2或保留<43的TOMM分数表明至少在另一个PVT上100%失败,这表明有足够的无效证据.
结论:
- 虽然建议使用多个PVT,但TOMM故障,特别是在特定的得分值,可能足以确定当多个PVT无法使用时的响应无效性.
- 需要进一步的研究来验证这些发现在不同的PVT和人群中.

02:40The Scientific Method
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
01:14Errors In Hypothesis Tests
When performing a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis and the decision to reject or not.
01:26Exercise Stress Test
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

01:20Psychological Responses to Stress
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...
